Class width circuit (in Buno, the code is 17-1i plus power supply terminal, 17-2 is minus upper power supply terminal.Each armature winding 1-1..., 1-5 is the connection point between the windings. The above-mentioned semiconductor rectifier 4 is connected to the terminal.The semiconductor rectifier 4 shown in FIG. This case will be explained later, and first the construction of the brushless motor will be described in detail in Figures 5 to 7.
This will be explained using diagrams. The motor shown in Fig. 5 is an axially flat type brushless morph M model, which is formed by soft plate press processing and has six disc-shaped mild steel plates on the lower surface of the knob-shaped housing 5. It is press-fitted and fixed to form an axially flat brushless motor body. A fixed bearing 7 is located approximately at the center of the housing 5 and the mild steel plate 6, and the bearing 7 rotates l1I.
III8 is rotatably supported on the shaft. A disk-shaped yoke 9 made of a mild steel plate or the like is vertically disposed on the rotating shaft 8.

As shown in FIG. 6, on one side of the yoke 9, for example, an annular field magnetic pole 10 having 1ζ6 magnetic poles and magnetized to N and S with an opening angle of 60 degrees is fixed. The armature 1 is disposed on the inner surface of the soft <nll plate 6 so as to rotate relative to the field magnetic pole 10, facing each other. They are spaced 6'U apart at equal intervals to avoid overlapping, and the conductor parts (radial conductor parts) effective for torque generation are
The opening angle width is approximately the same as the magnetic pole width of the B pole 10, for example, 60 degrees. A large number of windings are formed in the shape of a fan frame, and 7 pieces are formed.
The arrangement is Jn with an equal pitch of 72 degrees. Arranged in this way,

It becomes.

The semiconductor rectifier 4 described above is required to suitably adjust the current in 10 directions to vILζ. In the above, description will be omitted, and the semiconductor rectifier device 4 shown in FIG. 3 will be described below. Reference numeral 11 denotes a position detection element, for example, a Hall element 2 having four terminals is used.

The Hall element 11 is disposed at a midpoint position between the two resistors 1 and R2. This ball element 11 is formed by winding it into the fan frame shape as described above, and is pre-wound by an electric motor.・、
Military armature windings 1-1° . . . , which are located at the same position as the radial conductor portion contributing to the generated torque of 1-5, are arranged in the IS. The Hall element 11 detects the N and S poles of the field magnetic pole 10 (~, the adjustment γf+fi device 4 is used to detect the current flowing in the direction of the direction of the current in the winding 1-1...・The flow rate r is determined in 1-5.The output waveform from the Hall element 11 is shown in Fig. 4 (
It appears as shown in a).

Reference numeral 12 denotes an inverted ρ width circuit, which amplifies the output from the Hall element 11, and the output waveform from the circuit 12 appears as shown in FIG. 4(b).

13 is a current amplifier circuit, and the output waveform from this circuit 13 appears as shown in FIG. 4(c). When the Hall element 11 corresponds to the S position of the field magnetic pole 10, that is, when the S pole deviation is detected, the output of the Hall element 11 is jJ3;.

1-3, the current is vILn, and the torque cannot be increased depending on Cn. Similarly, since connection points 16-4 and 16-5 are at four points, no direct current flows through Denyomaki Hibikikatsu 1-5. That is, in the above-mentioned case, the potentials of the connection points 16-1 and 16-5, 16-3 and 16-4 are different, so that the armature winding 1-1. Only 612 units of l-4 have direct current.

It has the disadvantage that the higher the number of urine τ and the higher the number of urination steps, the more the number of elec- tronic windings that are not energized also increases.

The present invention has the above-mentioned shortcomings, and it does not have the above-mentioned drawbacks, and it provides a 5-phase 5-phase motor instead of a commutator motor.

The number is extremely small compared to the one shown in the figure. In the present invention, as the number of armature windings increases, even if there is even one armature winding that does not cause an electrocardiogram, such cases are considerably reduced. The number of magnetic poles of the field magnetic pole 10 also increases in proportion to the number.If the number of magnetic poles is increased in proportion to the number of magnetic poles, the time during which the width of the path will not be changed without compromising the armature is only a short time (between rotation angles), and then the armature winding 1vc; There is no element that is more important than being able to become an electrician. Therefore,
The armature winding 1 can be used effectively, a sufficient torque basin can be generated, and an extremely efficient five-phase brushless motor can be obtained. The present invention has been explained above by applying the duck direction flat type brushless motor +f.
It is applicable not only to this type of motor but also to cylindrical (cup-shaped) brushless (semiconductor) motors. The opening angle of the child wire 1 is approximately the same as the pole width of the field magnetic pole 10, but ideally it is necessary to do so, but in the present invention, the armature winding 1 is overlapped. It goes without saying that this also applies to cases where the opening angle of the magnetic field or the opening angle of the magnetic field is not approximately the same as the field magnetic pole.
